RESILIENT TIRE.

Specification of Letters Patent.

Patented Nov'. 23, 19ML Application filed October 17, 1914. Serial No. 867,088.

To all whom it may concern Be it known that I, EDWARD WALTER PRICE, a citizen of the United States of America, and a resident of the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, have invented certain ne\y and useful Improvements in Resilient Tires; and I hereby declare that the following is a full, clear, and exact den the draw-ings: Figure 1, is a vertical.-

section taken on the line a-a, Fig. 2; Fig Q, is a vertical section taken on the line b-b, Fig. l; and Fig. 3, is a fragmentary detail view of the interlocking ends of two adjacent joint covering plates, on a larger scale than the other views.

Like characters of reference refer to like parts throughout the specification and drawings.

The tire is composed of a set of tubular tire sections a, arranged in the form of an annulus, these tire sections being normally separated from each other so that they can freely expand and contractV during their flexion under the iniuence of the load; spaces c, between them, heilig provided for that'purpose. Contained within each tire section a, are two radially-alined spring plates (Z, 0V, of a curvature corresponding to the inner surface offthe tire section 'and in Contact therewith. These plates, as shown in Fig. 1 of the drawings, are nearly semi-circular in shape, and their edges are separated from each other by a normally unoccupied space d, so that the outer plate d will have a limited vinward movement Aduring the inward flexion of the tire section.

Extending inwardly from each ofl the4` platescl, d', are flanges e, e', respectively; the flanges of the'plate d bein'g separated from and substantiallyparallel with those of the plate d. Interposed between the flanges e, e', are two sets of auxiliary springs f, f which, by pressing against the flanges, co-

operate with the compression spring g in resisting the inward flexion and assisting the outward' flexion of the tire section. Each of the plates d, al has a projecting part It, to overhang the adjacent portions of the auxiliary springs and limit the lateral or bending movement of these springs when the coils are compressed. The ends of the compression spring g of ycach tire section bear against the plates i, i', and the ends of the plate t', at the inner end of the compression spring, overlap the edges of the adjacent tire sectionsand interlock with the adjacent edges of the plates z' of the adjoining tire sections, as shown at i in Fig. 3, the interlocking edges being secured together by rivets jl' to make a continuous band of plates t' around the inner circumference of the tire sections, and thus maintain them in their as sembled relation, the plates e" at the outer ends of the compression springs being so arranged that the'tire sections can freely respond to the inward and outward fiexions.

Partly inclosing the tire section a is a covering le of leather, or like material, and inserted through the covering le are spacing and guiding pins Z which extend through the spaces c between the tire sections to maintain the spaced relation of the compreventing the lateral movement of the coils of these springs during their compression and expansion. Partly surrounding the tire sections and their covering 7c is a rubber shoe m which may be made after the manner of any of the usual rubber tires.

When the tire is subjected to a load, the tire sections in contact with the roadway yieldinwardly and compress the springs g and auxiliary springs f, f to the limit of the load imposed on them or to the limit permitted by the guide posts o, o', secured to or integral with the plates e', z", and extending inwardly from the plates d, d', respectively; theseguide posts o, o being normally separated so 'that the tiresections can yield inwardly under the influence of the load untilthe inner endsof the guide posts comeinto engagement. To render the con* tact of .these posts noiseless, their inner ends may be providedwith rubber or fiber tappets o, and to permit ofthe ends cf these `parts coming into contact during the inward ends of the posts. When each tire section is relieved of the weight of the load during the revolution of the wheel, its compres sion and auxiliary springs, press the tire section outward to its normal shape.

What I claim is:

1. A resilient tire comprising a plurality of independent tubular tire sections, a pair of radially-aimed curved plates within each section, a compression pair of plates against the inner surface of the tire section, flanges extending inwardly from the curved plate on each side of the compression spring, and auxiliary springs engaging said flanges on opposite sides of the compression spring.

2. A tire comprising a plurality of independent tiihular tire sections normally separated from each other for expansion and contraction during ,their radially-aimed curved plates within each section and normally separated from each other so that the outer plate will have a limited inward movement during the inward flexion of the tire section, a compression spring pressing each pair of plates against the inner surface of the tire section, plates at the inner ends of the compression springs overlapping the edges of the adjacent tire sections and interlocking with one another, flanges extending inwardly from the inner surfaces of the curved plates .on opposite' sides of the compression spring, auxiliary springsgengaging said flanges on opposite l sides of the compression'sprihg to assistits action, and a tubular cover inelosing the' tire sections.

3. A resilient tire comprising a plurality compression spring, spring pressing each flexion, a. pair of of independent tubular tire sections, a pair of radially-alined curved plates within each section, a compression spring pressing each pair of plates against the inner surface of the tire section, llanges extending inwardly from the curved plate on each side of the compression spring, auxiliary springs engaging said flanges on opposite sides of the and posts extending in'- wardly from the radially-alined plates into the ends of the compression spring.

1l. A tire comprising a plurality of'independent tubular tire sections normally sepa` rated from each other for expansion and contraction during their flexion, a pair of 1adially-alined curved plates within each section and normally separated from each other so that the outer plate will have a limited inward movement during the inward flexion of the tire section, plates at theinner ends of the compression springs overlapping the edges of the adjacent tire sections and interlocking with one another, flanges extending inwardly from the inner surfaces of the curved plates on opposite sides of the compression spring, auxiliary springs engaging said flanges on opposite sides of the conipression spring to assist its action, altiibular cover inclosing the tire sections, and posts extending inwardly from the radially-ahmed plates into the endsof the compression spi-ing.
